A distichous leaf arrangement is when the leaves along a stem are in two rows. Distichous is Greek for "two ranked". This is a common leaf arrangement in grasses or orchids. A good way to tell if a plant has a distichous leaf arrangement is to break off a section of the stem and lay it on the ground. If all the leaves are touching the ground it is probably disticous.
